To all 'ev/10ml vimay co'cewb:

le it known that I, LFRED J. A'VIvIAr citizen ot the United States,residing 1n the f vity and vounty of Denver' and State of thejconveyer,doubles the' coni'fe'yer-run Colorado, have invented certain newandnselul improvements in'l}o`. \*#Car Loaders; and l do declare thefollowing to be a full, elear,`ai1dl exact deseriptionof the'invention,such'ns will enable others skilled in the art to which itappel'tai-us'to make and'use thel saine', referencebeing had to theaccompanying;- drawings', and'to the charactrsf'of ref-' ereh'ce markedthereon, oit this specticati'on.

My invention 'relates -to im box Car-loaders; my object'bei'ng torov'ide an appi'u'atus of this characterA wbielh shall he comparativelysimple in e'onstru'etion, economical in cost, reliable, durable andeficient in use. y l

vj'ustment is effected by means of two blocks The longitudinal ad- 17freely slidable in the frame-members 15, the said blocksforming bearingsfor trunnions 18 secured to the main frame bymeans ofwsuitable fasteningdevices 19 passed through flanges 20 formed at the base or innerextremities of the trunnions. Each -block17 is freely slidable in itscorresponding auxiliary frame-member 15 and, is acf tuated to carry themain frame in either di rection by means of a screw 21 j ournaled in theopposite ends 22 of each auxiliary frame-member. At the forwardextremity cf one of these screws is applied a handwheel 23 for .manuallyrotating the screw.A The rear extremities of the two .screws areequipped with sprocket-wheels '24 connected by La chain 25 whereby, asone screw is turned, bo-th screws .will be rotated and impart uniformtravel to the blocks 17 where' bythe main frame is moved bodily eitherforwardly or rearwardly with referenceto the turn-table.

The manner of tilting the main 'frame upon the blocks 17 or withreference to the auxiliary frame will now be described. Secured to oneof the blocks 17 by means of suitable fastening devices 26 is averticallydisposed plate-arm 27 whose upper extremity is transverselyreinforced as shown at 28, this transverse portion being concaved andtoothed asshown at 29 toL receive a worm 30 formed on a shaft 31journaled in bearings 32 for-med on fone side of the main flange. Thetoothed upper vextremity of the plate-arm 27 lies in an arc struck fromthe center of the trunnions 18. The forward extremity of the worm shaft31 extends beyond the main frame-work and is fashioned as shown at 33 toreceive a crank or hand- As illustrated in the drawing, the auxiliaryframe 16 is composed of Vvertically-arranged suitably-supported parallelsteel tive sprocket-wheels constitute upper. and

lower supports at the rear extremity of the apparatus for the endlesslconveyer; while the forward extrem-ity of the conveyer is Supported onsprocket-wheels 46 fast on a -shaft 47 journaled inbearings 48 carriedby depending brackets 49 mounted on the forward extremities of twohollow bars 50 which telescope freely in hollow coperating `members 51secured to the inner surfaces of the oppositevside-plates 35 of the mainframe. telescoping' member 50 contains a solid block 52 having athreaded opening 4in which is threaded a longitudinally disposed screw53 which is journaled in the rear extremity of the main frame' as shownat 54. Similar screws 55 are journaled 1n the; lower part of `the mainframe and are threaded in blocks .56 slidably mounted on 'tracks 57secured to the inner surfaces of' the opposite side-plates of themainframe. Journaled in these blocks is a transverse shaft- 58 carryingsprocket-wheels 59 which are engaged yond the same and are equippedwith` sprocket-wheels 60 and 61, the fo-ur sprocket wheels being engagedby a chain 62 to cause the four screws to operate in harmony. Each screwextends rearwardly beyond its sprocket-wheel as shown at 63 and isformed polygonal, preferably square, in cross-sec- The rear extremity ofeach/ tion whereby 1t is adapted to receive a handwheel-or crank forsimultaneously operating vthe four screws of the apparatus.v

ybers 50 lto travel rearwardly, the bearingblocks s carrying the shaft58 with the sprocket-wheels 59 will be carried forwardlyv to take up theslack in the'conveyer caused by the rearward movement of thetelescoping'members 50.

Suspended fromthe lower platform 37 of the mainframe is a motor Gl(preferably electric) which is secured to said platform by suitablefastening devices 65. The armature shaft ilt of this motor is equippedwith a sprocket-wheel 67 engaged by a chain 68 leading to a largersprocket-wheel 69 fast on a shaft 70 journaled in the lower part-of themain frame. Upon this shaft is also mountedr a smaller sprocket-wheel 71connected by means of a chain 72 with a larger sprocket-wheel 73 fast ona shaft/74 intermediate the shaft GG and the shaft 70. Upon the outerextremity ofthe shaft 74 is a smaller sprocket wheel 75 which isconnected by means of a chain 76 with a sprocket wheel 77 fast on oneextremity of the shaft`-l1,

the conveyer.

whereby power is applied to the endless convcyer for imparting thenecessary movement thereto for carrying the'coal during the loadingoperation.

The telescopi'ng member 51` connected with each side-plate 35 of theframe, is provided with a flange 78 supported by a cleat 79 inV `aposition Slightly above the upper platform 86 of the frame whereby aspace 80 is left below the 'flange 78 and communicating with the opening81 which is adapted to receive the telescoping member connected with theconveyer asheretofore explained. This telescoping member 50 has a.flange 82 adapted to enter the space 80 and slide freely therein :duringthe endw-ise.- adjustment of The telescoping member 51 extends theentire length of the! upper portion of the lmain frame 16 and theflanges T8 of the two telescoping-members 51 form a support for thechains 44 of the conveyer, the hinge-pins 483 of the links 84carrying'rollers 85 which travel upon the flanges 78 until the cud ofthe main frame is reached, when the said rollers engage the flanges 82of the telescoping members 50, which anges support'the conveyer untilthe forward extremity of the members 50 is reached lwhen the conveyerpasses downwardly around the sprocketsl 7 6 i of the shaft 47.

From the foregoing description, the use 4and operation of my iiii[r0\'ed car-loader will be readily understood.

I In order to use the loader it is lirst inouted on a support-8G locatedoutsidethe car and provided with 'tracks 87 which the wheels S of thetruckengage, the said rails of thc `track being extended into the boxcarl RS. The loader whichis in the condition indicated by dotted lines,outside the car,'in Fig. 10-that is tosay, with its conveyer adjusted toreduce themacliine to its mini` in um lengthfis then run in to the carand turned upon the turn-table during its entering movement, after whichthe conveyer is extend.

ed until its forward end occupies a posit-ion -close to one end of thecar. This is accomplished by turning the screws 53and 55 in a' direction'tocause the structure composed of the telescoping members 50 to travelforwardly, while the structure including the slidable blocks 56 travelrearwardly. ln ordei to eect this result,.it is only necessary to apply-a crank or hand-wheel toone of the projections 63 of one of the screws53 or Theturni'ng of one of these screws in the proper direction willturn all thel screws in a direction to accomplisl'rtlic aforesaid resultby virtue of the connection of vthe four sprocket-wheels G0 andl, bymeans of the chain 62. rlfhe forward extremity of the conve-yer is thenlowered to :i position close to the bottom of the car. This isaccomplished by turning the shaft 31 whereby t-he worm 30 is caused totravel on the curved toot-hed upper extremity of the plate-arm 27, inthe proper direction. During this operation, the trunnions 18 of themain frame turn inthe blocks 17 of the auxiliary frame by virtue'of theconstruction heretofore described. As'soon as this is accomplished, themotor 64 may be set in motionwhereby 4motion is' communicated to theendless cn- 'veye.r. The coal or other maten-iai to be the rear end ofthe conveyer fromia chute 89.

' The coal may be continuously fed `through thechute to the co'nveyer,which. being in constant motioncarries itto the end ofthe car anddelivers it to the floor thereof. In this manner the coal is carefullydeposited in the car without any opportunity for breakage ortheproduction of slack. As the end of the car fills, the forward extremityof the conveyer is gradually raised and when the coal has been depositedin the car end to the desired depth, the forward extremity of theconveyer is retracted or withdrawn. In this manner the car -is graduallykfilled from the end toward thecenter until the forward extremityl ofthe conveyerhas, by virtue of the adjustment heretofore explained,reached its rearward limit of movement.

'lhe main frame may theny be retracted bodily or moved jrearwardly uponthe auxiliary frame .16 mounted on the tur1i-table,'this operatxon beingaccomplished by turning one of the screws 21 whereby motion is impartedto both screws through the instrumentality of the connecting chain'25.As these screws 21 are turned in the proper direction, the mainframe-work, together with vthe mechanism mounted thereon, is caused totravel rearwardly' on theA auxiliary frame '16. to the 'position shownin Fig. 2, thus'making it practicable to deposit the material'in thecarquite closely tothe center thereof.' After the filling of the carfrom one en tothe central part is accomplished, the apparatus is movedto its original position lwli-ile entering the car-door and is turned ina direction to fill the oppositeV end of the car, when vthe operationheretofore ldescribed ".tion, which has been occupied by the loader,

` filled if desired by the direct action of the chute 89. l

The upper platform 36 occupies a position just below and in closeproximity to the depending partsof-the angle-iron conadapted to catchany fine coal that may eslcape between the slats or bars connecting vthechains of the conveyer, thus ,preventing any tine coal 4from passingdownwardly and interfering with the operating parts of the machine.Furthermore, by virtue. of the arrangement of the upper run of thetraveling conveyer with reference to the upper platform, the slats orbars of the conveyer are adapted to scrape any tine coal that otherwisewould accumulate thereon, forwardly when the conveyer is in operation,the said coal being carried as far as the forward extremit of the mainframe when it drops into t e ca'r beyond the operating mechanism ofthe'l loader.
